How to write a function that can calculate power in Java. No loops

Question

I\'ve been trying to write a simple function in Java that can calculate a number to the nth power without using loops.
I then found the Math.pow(a, b) class...

Answer 1

Try with recursion:

int pow(int base, int power){
    if(power == 0) return 1;
    return base * pow(base, --power);
}
